Unformatted text preview: greater than dtrans. At time t=dtrans, where is the first bit of the packet? f. Suppose dprop is less than dtrans. At time t=dtrans, where is the first bit of the packet? g. Suppose s=2.5*108, L=500 bits, and R=128 kbps. Find the distance m so that dprop equals dtrans. Solution: d prop = m / s a. seconds. d trans = L / R seconds. b. c. d. e. f. g. d end −to−end = ( m / s + L / R ) seconds. The bit is just leaving Host A. The first bit is in the link and has not reached Host B. The first bit has reached Host B. Want L 500 m= s= 2.5 × 108 ) = 977 km. 3( R 128 × 10 Problem 3 (15 Points): A packet switch receives a packet and det...
